I use Gobbler. I also use Box, Dropbox, and a couple other cloud services. Some are paid, some are the free intro accounts.
Even if they ALL closed their doors tomorrow I'd still have all my data, and in fact thanks to cloud storage my data is stored in more places than ever. It is a clear win as far as I am concerned.
Certainly it would be a lot more work for me to keep all my storage synchronized, but the main thing is that I still have all my data. I am not dependent on them for that piece at least.
I think Gobbler made a huge misstep with their announcement about ending Gobbler 1.0. I have no idea what they were thinking, but I'm glad they made the course correction as quickly as they did.
As far as where they store the data, again I could not care less, actually, I think I'd prefer that they focus on the application, and let others who are experts on data centers and data storage take care of that aspect.
It is a huge black eye for Gobbler, although I'm not quite ready to give up on them. It is a smaller black eye for Cakewalk, but they'll survive it.
